Definitions

  • the invention relates to a device for emergency manual operation in the case of switching magnets, whose armature in the pole tube by the force of a spring arrangement in an end position and by magnetic field excitation against the spring force into a second End position is movable, with a tension member axially displaceable in the pole core, which is movable by means of a manual actuating device and one with the anchor cooperating driver to this against the spring force to move to its second end position.
  • the invention has for its object a device for emergency manual operation to create, which are compared to the known such devices characterized by a simpler structure and reduced assembly effort.
  • this object is according to the invention solved in that the armature, the pole core, the spring arrangement, the Tension member and the actuator to a prefabricated unit in Form of a cartridge are united by the inner, open end of the pole tube forth in this can be used and connected to it that the pole core Pole tube closes at its inner end.
  • connection to the pole tube is particularly simple if the pole core has an annular groove worked into its circumference and through Crimping the end of the pole tube into the annular groove can be connected to it.
  • the actuating device can be used as Actuator for the axial displacement movement of the tension member a threaded bolt have a guide for the with an internal thread section Interacting axial hole in the pole core.
  • the emergency operation can be convenient and safely done by manually turning the threaded bolt, if this has a screw head accessible at the free end of the pole core has, for example, be provided with an extensive knurling can.
  • the tension member is preferably a one-piece extension of the threaded bolt formed, which extends beyond the inner end of the pole core into an anchor trained axial bore extends.
  • the extension of the threaded bolt forming the tension member preferably has which is due to a sealing arrangement located in the axial bore of the pole core extends into the axial bore formed in the armature, an outer diameter tapered relative to the adjacent part of the threaded bolt on. This ensures that there is also an emergency operation can easily be managed against high prevailing working pressures.
  • the assembly is particularly easy if as a driver a free end of the extension of the tension member flared rim is provided.
  • a shape of the free end of the tension member is particularly easy to manufacture during assembly if the free end of the Tension member has an axial blind bore and after assembly of the individual parts of the cartridge-like assembly, the mouth of the blind hole is deformed outwards as a flanged edge.
  • the invention is based on one shown in the drawing Embodiment explained in detail.
  • the magnet is one of the so-called "pulling" type, i.e. his anchor 3, which is by means of a spring arrangement 5 is pressed away from the pole core 7 into an end position, which is shown in FIG. 1 is shown, when the magnetic winding is excited against the force of the spring arrangement 5 pulled to the pole core 7, as shown in Fig. 2.
  • the pole tube 1 is for magnetic decoupling through a welding point 4 divided.
  • the armature 3 is over a spring ring 49, which is seated in an annular groove 9, which in an axial bore 11 the armature 3 is formed, connected to an actuating pin 13, see in particular Fig. 3.
  • the actuating pin 13 points for the interaction with the spring ring 49 also an annular groove 35 and extends from Armature 3 away beyond the adjacent end of the pole tube 1 and serves as Actuator for a relevant switching operation, for example Valve actuation in a hydraulic system.
  • FIG. 4 All the individual parts accommodated in the interior of the pole tube 1 form one prefabricated, cartridge-like unit, which is shown in Fig. 4 for itself.
  • This cartridge is from the open end 15 of the pole tube 1 in this way used that the pole core 7 closes the pole tube 1 at the end 15.
  • the connection between pole tube 1 and pole core 7 takes place by crimping end 15 of the pole tube 1 in a circumferential annular groove 17 of the pole core 7.
  • Another circumferential annular groove 19 in the pole core 7 takes an O-ring 21 for the seal between pole core 7 and pole tube 1.
  • the cartridge shown in Fig. 4 contains in addition to the pole core 7, the armature 3, the attached actuating mandrel 13 and the spring assembly 5 also a device for emergency manual operation.
  • This has a threaded bolt 23 on, the threaded portion 24 with an internal thread 25 in an axial bore 27 is screwed into the pole core 7 and one at the end of the pole core 7
  • Accessible screw head 29 which has a knurling for the manual rotary control is provided.
  • the threaded bolt 23 is on its side facing away from the screw head 29 extended by a tapered end portion 31 which extends through a sealing arrangement 39 passing through an enlarged portion of the bore 27 of the pole core sits, extends into the axial bore 11 of the armature 3.
  • the free End of the extension 31 passes through a local constriction 43, through which in the bore 11 a facing the pole core 7 first annular shoulder surface 41 and a second annular shoulder surface 45 facing away from the pole core 7 is formed, which is best seen from Fig. 3.
  • the free end of the extension 31 has an end-side, coaxial blind bore 50, the mouth of which is flanged to form a flanged edge 47 to the outside.
  • the flanged edge 47 forms a driver which at one Emergency operation, i.e. when unscrewing (upwards in the drawings) of the bolt 23 on the annular shoulder surface 45 of the local constriction 43 of the bore 11 of the armature 3 comes to rest against it the force of the spring arrangement 5 pulls on the pole core 7. This position the individual parts is shown in Fig. 4.
  • the length of the tension member is dimensioned so that the end flanged edge 47 of the extension 31 when the screw bolt 23 is screwed in, ie not activated manual override (Fig. 1 to 3), in such a relationship to Ring shoulder surface 45 is that the normal working stroke of the armature 3rd is possible without hindrance.
  • the compression spring arrangement 5 is in the Axial bore 11 of the armature 3 on the one hand on the formed by the constriction 43, the pole core 7 facing ring shoulder surface 41 supported while the other end on one lying against the sealing arrangement 39 in the pole core 7 Washer 51 is supported.
